Hierarchically porous carbons derived from polyaniline by “nanotube seeding” for high-performance ionic liquid-based supercapacitors†
Abstract
We demonstrate the outstanding combination of ultrahigh energy density (199.11 W h kg−1) and capacity retention (90.5%, 10 000 cycles) of ionic liquid electrolyte supercapacitors based on novel hierarchically porous carbons derived from polyaniline nanorods by “carbon nanotube seeding”.
